In this youth-oriented culture, a 40th birthday often is viewed as a reason to duck and cover. But the birthday child in this case is PBS Hawaii, so bring on the hats and horns!

There's ample reason to celebrate the longevity of the Islands' public broadcasting affiliate, known for most of its life as Hawaii Public Television. It has survived with dwindling taxpayer support: The state-funded station finally transitioned into a private nonprofit six years ago.

Nevertheless, PBS Hawaii's commitment to public affairs programming remains just as strong today. Most recently its studios became the venue for the lone televised debate in the U.S. Senate Democratic primary.

Going forward, the station needs more public support for its planned conversion to digital broadcast technology and wants to expand locally produced shows. One star on its current menu: the traveling educational outreach program "Ready To Learn," which gives teachers a boost with tools and strategies and involves more parents in the process.

Viewers should reflect on their favorite offering, whether it's "Sesame Street," "Antiques Roadshow" or something in between. Then, they should show their appreciation with a donation in the next pledge drive.

Happy birthday, PBS Hawaii. May the happy returns keep coming for us all.
